We pulled the official install counts, satellite sun records and today’s capped prices for 30 UK towns where solar genuinely pays. Pick yours — the percentage shows how many homes there already generate.
Bills went up again this winter. The price cap rose 4% on 1 October to £1,723 a year for a typical home — the fourth winter running above pre-crisis prices — and it resets again on 1 January. Every kWh your roof makes is one you never buy at 26.32p.
